I Desperately Need Help.

Can someone please help me with the 101979912-86-matte-transitions-pack!

I've followed the video tutorial but I get a black screen where the other image is supposed to be during the transition. How do I make the effect display the image instead of a black screen?

I'm using Adobe After Effects CS6.0. I'm also a beginner with the program.

Hey, not sure what you're referring to but if nobody responds you should search for YT tutorials.
